TURBINE.

To all whom it may concern:

Be it known'that we, WILLIAM S. ELLro'r'r and FRANK M. FABER, both of Pittsburg,

Allegheny county, Pennsylvania, have 1n-.

similar to Fig. 1 showing a further form of the invention.- Fig. 7 1s a cross-section on the line VII-VII of Fig. 6.

Our invention relates to the class of turbines, more particularly those intended for driving tools for removing scale or sediment from the'interior of tubes.

The object of the invention is to provide a simple and efiicient turbine and shaft which will belon er lived than formerly, and in whichthe s ocks upon the cutting'head are largely absorbed or cushioned before they can reach the turbine wheel.

Heretofore in this class of devices when used in connection with cutting heads the shocks andjars upon the head have caused rapid deterioration of the turbine driving device, making the turbine short-lived. Our

invention greatly reduces this difficulty, and consists in the construction and'arrangement of parts as hereinafter more -fully describedand claimed.

In the drawings, referring to the form of Figs. 1, 2 and 3, 2 representsthe cylindrical turbine casing having an inner concentric shell 3, which'is preferably cast integrally with the casing to which it is connected by the opposite webs or ribs 4 and 5 as shown in- Fi 3. Within the inner shell 3 we preferab y lace a bushing or lining 6 having a rear shou dered portion 7 which fits a ainstthe rear end of the inner shell, this s ell being shorter than the casing and projectin be-' yond the front end of the casing in this orm.

Within the bushing 6 fits the turbine shaft 8,

the rear end of which is screwed or otherwise secured to the turbine wheel 9. This tur bine wheel is preferably provided with a circular recess in its front portion, forming an Specification of Letters Patent.

annular fiangelO Within-which is seated the ring 11 of hgnum-vitae. This lignum-vitae bears against a ring 12 which fits a ainst the rear end of the shoulder of the bus ing.

At the rear end of the turbine wheel it is provided with a shallow circular recess containing a plate 13 fitting upon a circular lignum-vitae block 14, which is fitted into a recess in the stationary portion 15 of the turbine. This stationary portion 15is provided with the usual ports. 16 and. is referably of ring form,-fitti ng against a shou der 17 in the rear end portlon of the-casing, and pressed against said shoulder by the screw couphng, 18 which is secured into the rear end of the casing.

The bushing 6 is held against rotation by any suitable means, such asthe screw 19 extending through one of the webs and entering a hole in the bushing, or it may be pressed in.

I preferably provide means for supplying oil or a lubricant to the long shaft extending through the out-bored bearing for the turbine shaft. In the form shown an oil chamber 20 is formed by boring or coring a holelongitudinally into the web or partition 4 and Inserting a hollow plug 21 in its outer end.

'The plug is chamfered on its inner side to form aseat for a ball-valve 22 which is normally heldclosed by the spring 23 extending through the oil chamber. Holes 24 connect the oil chamber with 'annular' recesses 25 in the inner'shell of the casing, from which holes 26 lead through the bushing to the shaft 8. Oil-is inserted by pressing thevalve back with the tube of the oil can and forcing oil into the chamber. When the valve is released it immediately closes the oil chamber and the oil gradually works through the holes I onto the shaft.

Any suitable cleaning tool may be attached to the turbine, and I have shown a drill-shaped device-27 connected to the shaft by universal coupling 28. Y

It will be noted that in Figs. 4 and 6 the turbine wheel is provided with journals at both sides, the front journal being long and which takes up theshocks on the tool. By unscrewing the rear coupling the stationary part of the turbine may be pulled out and the wheel unscrewed from the shaft and also drawn out.

In Figs. 4 and 5 we show a shorter form of the turbine, in which the casing 2 is provided with web's 4*v and 5' as before. In this form the rear coupling 18 is screwed in to clamp the'stationary portion of the turbine, which is forced againstthe shoulder17 in the casing. The turbine wheel 9 is not provided witha thrust bearing in front thereof, but thrust bearings are provided for the shaft 8 on'each side of the stationary turbine portion. Thus, we show this stationary portion as having a rear annular extension 29 forming. a chamber" which is normally closed by a screw-cap 30. Within this chamher a bottom-ring 31 of lignum-vitae is seat,-

ed, next to which is a brasswasher 32 held by a nut-and lock nut within the chamber. At the front of the stationary turbine portiona lignum-vitae washer 33 is seated in a'recess in the stationary portion, while a lignum-vitaa ring 34 is seated in a recessin the turbine Wheel. A- brass ring 35 is laced between these lignum-vitae s, t us forming the stationary turbine ortion. In this case the oil valve 22 is int e form of a plug inweb 39 and normall bine wheel, which cushions the jars and stead of a ball, and the oil flows into a chamber 36 extending-along the removable bushing 6*, through holes in which the oil flows to the enlarged portion of the shaft 8%.

In Figs. -6 and 7 I show a form similar to that of Figs. 4 and 5., except that the closure at the rear end of the casing is of different form. In this casethe screw-coupling.18 is made in the form of a plug with a central hub 37 containing the chamber 38 for therear bearing of the shaft 8 "portion is carried on radial webs 39 and 4:0,

I do not claim herein s ecifically the forins of Figs. 4, 5, 6 and 7, as t e same are claimed in another co-pending application -'No.

350,246 filed December 31st, 1906. The advantages of my invention result from the simplicity-and solidity of the construction. vA long out-bored bearing is pro-v vided between the external tool and the turn shocks, thus greatly saving the wear of the turbine. The thrust bearin s absorb the end thrust of the shaft, and the 'gnum-vitae and metal washers are long-lived and give little friction. The oiling device afio'rds a steady supplg of oil to the long shaft bearing, and

the evice is compact and strong. The washers may benietal or wood, and may be varied in size, shape and number.

Many variations may be made in the form and arrangement of the parts without departing from our invention' a. thrust bearing for thee aft on both sides of.
